    • The battery may be completely drained when using the Walkman for the first time or after an extended storage period. If this is the case, the display will not appear on the screen when you first start charging but will appear after about 30 minutes of charging.

      • Do not use a charge-only USB cable or a USB cable with no data transmission functionality.
      • The Walkman won't charge when the computer is in sleep mode, even if you connect it to the computer. Be sure to cancel the sleep mode before attempting to charge the Walkman.
